Unusable Network Drivers for RHELv5.1 64-bit
With Sun Installation Assistant
After installing and configuring Red Hat Enterprise Linux (RHEL) v. 5.1 (64-bit), the
network devices are there and mapped as expected, but the interfaces are non-
functional.
This issue occurs with the following configuration:
■
Network cables are not plugged into all NICs.
If the network cables are plugged in all NICs, this problem does not occur.
■
User chooses to activate all NICs on boot.
If user chooses to activate only the NIC with network cable plugged, this problem
will not occur.
■
User configures all NICs with static IP addresses.
This problem will not occur if DHCP is chosen.
■
User configures the same network/gateway for all NICs.
If different networks are configured for different NICs, this problem is not seen.

Workaround
After booting the installed system, perform the following:
1. Log in as root.
2. Enter the
ifdown
command for all the interfaces.
ifdown eth0
ifdown eth1
ifdown eth2
ifdown eth3
3. Enter the
ifup
command for the interface with network cable plugged in.
For example:
ifup eth0
At this point, the network should be up and running.
4. To make this configuration persistent across reboots, you can make only the
interface with network cable active on boot by doing the following:
a. Change to the
network-scripts
directory.
cd /etc/sysconfig/network-scripts
